New issue 3204 by [email protected]: Users of range analysis results assume SSI, but we have only "adhoc SSI in random places"
http://code.google.com/p/v8/issues/detail?id=3204

The range information on values can depends on conditions, which is incompatible with our "sometimes SSI, but not really SSI"-graph. For example, the following function illustrates the issue:

function ModIRightCanBeZero() {
  var x = 0;
  for (var i = -1; i <= 0; ++i) x = (2 % i) | 0;
  return x;
}

This will crash right ahead when optimized.
